the stationary portion or portions of the trackway, or to be disconnected therefrom. A number of over-head traclrways may be used; one above the other, such as maybe necessary in abuilding having a number of st'o'r-ieswith a stationary trackwayin each story, and the movable portion of the tracls way is to'be'raisedand lowered to align-with either of the stationary trackways in-the dift' ferent stories, onto be disCOn-nectedthere from-,as may bereq'uiredto transfer the trolley or trolleys from any one of said station: ary trackways to any other. H y

The principal ob'ect-of' my invention-is to provide an improved form of; stops to prevent the trolley ortrolleys from running off the ends of the traekways hen'out of alignment with a 'co-ope'ratingportion, and to also permit said trolley 01' trolleys-to pass freely over the co-opcratin'g portions ofsaid trackwayswhensaid portions are in proper alignment with each. other, the operations of said step devices being automatic and simultaneous, as the movable portion of thetrackway elevated or lowered from one position to another and into alignment with stationary sections of" trackways. My improvement also'consists of novel details of construction which willbe hereindescribedand definitely set, forth in the claims.

In the accompanying drawings, forming a part of this specification,- Fig. 1 is aside elevation,partly in vertical section, of a portion otan overheadcarrying equipment embody ing n ry invention, which willbe more fully explained-hereafter. V Fig. 2 is ahorizonta l section on line 2+2 of Fig. 1; looking in the direction ofthe arrows, the parts cutaway in F 1 being replaced to makethe structure coimp -lete. Fig. 3 is an enlarged plan viewof the operating portions of the stop devices, a portion of the movable and the stationary traclrways bein shown in alignment with eachothenI-and the stops being swung up, to one side tol'permit -the' trolley to pass from 1928..

Fig. 5 is the same showing the stop raised to one side to permit 'the trolley to pass on to a cooperating trackway which is not shown.v Fig. '6 is an end view of it, in other words, a View looking directly. at the near; end of the trackway'witn the stop mechanism ,attached; Fig. 7 in detail view which, will be hereafter 'explained. i V i Referring to the drawings, No. l O represents the movable portionv of the'traclrway which is preferablyconnected to the support 11 by a series of liangers 12. In order that saidflmovable tracksection mayfbe disconnected froni the stationary sections 13, and be raised and lowered to align with other track sections above or below, such as 14; shown above in Fig. 1, it ispreferable that a frame composed ofside members 15- and end members l6ibe provided,;to which frame the supporting member 1.1 may be connected, as most plainly shown in Fig.2. Furthermore,-

tohold this framein place in its movements .up and down, vertlcally disposed members 17 may be used. 1

, It is preferable tohaveiour ofthese members 17, one at each corner of the frame car rying the supporting member 11 with the track section 1O. These guide members, as

they may be called, may be'connected to beams in each of the floors in the building in which they are used, or they may be'otherwise supporterhand there must be anopen space between them from the top to the'bottom for the passage up and down or the frame carrying the track sectionlO. Also, additional guiding members 18 may be applied to the inner sides of'the members 17, and co for the track sectionlO to (Io-operate with tions of the trackways andtheir mechanism operating-guidingmembers 19 maybe at tacked to the corners of the frame 15 and 16 run the members 18, as most plainly shown in Fig. 2. It is furthermore preferable that the members 11 and 19 be made of channel iron. The frame carrying the track section may be raised and lowered in any suitable manner, such as by cables 20 attached by clips to the supporting member 11, as shown, or otherwise, and then be connected at their upper ends tosuitable hoisting and lowering mech anism.

The different stationary track sections, 13 and 14, and as many others as may be used in the different stories of the building, may be supported in any suitable manner, like the supports of the movable track section 10 to the member 11, or otherwise, but at the ends of the track section 10, and also on the ends of all the other co-opeiating track sections, it is preferable to have special hangers 21, which, besides effectually gripping and holding the trackway, will also be adapted to be suitably connected to the members 22 which carry the stops 23 and also the mechanism for operating them. As before stated, these stops always operate in pairs and with each other, so as to prevent the trolleys from running off the ends of the 'co-operating trackways when not in alignment, and each 1 member 22, besides carrying a stop 23 and the mechanism for operating it, is also pro.-

videdwithmeans for simultaneously operating the stop mechanism on the adjacent member 22, for which purpose these members are placed in reverseposition, as shown in Fig. 3.

As will be seen most plainly in Figure 3, the stop members 23, which are shown in open position,have their inner ends rigidly secured to the outer ends of shafts 24 which are shown in Figs. 4, 5 and 6, but not in Figure 3, said shafts are each journaled in a central portion of the members 22 and at approximately right angles thereto. On the opposite or. meeting ends of each of the shafts 24, partial cog 25 are mounted, or in other words, castings which have semi-circular portions with gears part way around. These gears are meshed in similar adjacent gears 26 which are formed on members 27 and are provided with long cog portions 28 to limit the revolutions of the co-acting cogs. The members 27 are journaled on cylindrical portions 29 of the members 22, and are provided with outstanding portions 30 which, when the track sections are in alignment, are adapted to come into contact with the outstanding portions 31 of the opposite member 22. The co-operating mechanism of the track sections being reversed to co-operate, some of the parts are below and cannot be shown in Figure 3.

The upperand lower ends of the outstandportions 31 are beveled, as shown in Figs.

4, '5, (Sand 7, and when the co-operating track sections are brought into alignment by the movement of the track section 10 from either below or above, the outstanding opposite portions 30 of the members 27 will be brought into contact with the bevel edges of the portions 31 and will be pushed either up or down accordlng to the up or down movement of the track section 10. This will cause the member 27 to rotate to a certain extent in the same direction, and the cogs 26 on the members 27, being in mesh with the cogs 25, will cause them and the shafts 24 to which they are fixed to also be rotated, and the stops 23 will be simultaneously swung to the side, as shown in Fig. 3, thus clearing the trackway for the passage of the trolleys.

When the movable track section 10 is be low and is moved upward, the upper edges of the parts 31 which it carries, coming in contact with the parts 30 on the other sections, will move these parts 30 upward, which will cause the co-operating gears 25 and 26 (see Fig. 6'), to rotate, and this will rotate the shafts 24 carrying the stops 23 on the stationary sections 13, and will cause them to be swung to the side, as shown in Figs. 1 and 3. At the same time and simultaneously, the parts 30 on the movable section, coming in contact with the under sides of the parts 31 on the stationary sections, will be pushed downward, and this will cause the co-operating gears 25 and 26 to rotate, which will. also rotate the shafts which carry the stops 23 on the movable section, which stops will be simultaneously swung to the side, as also shown in Figs. 1 and 3. WVhen the movable section is above and is lowered into alignment with the stationary sections, all the movements will be reversed, and the stops will be swung to the opposite side of thetrackway, as shown in Fig. 5.

As shown by Fig. 7, which is a perspective of one of the members 22, a lower central. portion of the member is extended downward to form the opening 32 in which the shaft 24 is journaled. As this shaft is horizontally disposed and mounted above and in line with the track section, and also above the hanger 21 connected to'it, the upper end. of the hanger connected to the member 22 is preferably spread apart, and the upper ends of the hanger, which is preferably made of two parts, which are made to straddle the downwardly extended portion having the opening 32 and said upper ends are extended laterally to receive the bolts 33 by which the hanger 21 is connected to the member 22. It is also important that the hanger 21 be securely attached to the track section because it is close to the stop 23, the lower end of which may be bumped against severely. It is therefore preferable to use two or three bolts 34,

trackways carrying the stop devices are connetted-i The portionsBO are pre-ferablymaide hollow to saveman, The invention is e trem-ely simple, easilycenstructedand inofhis step mechanism, 'but thefun 1 moved into saidline of travel, to prevent the trolley from running off the open end of the trackway. Any co-opelrating mechanism of the stop devices that, of itself alone, and

without the aid of other parts, will simultaneously cause this result, will be within the scope of the invention.
